Which of the following is NOT a permissible form of photo ID for pilots?

A green card, or Permanent Resident Card, is not recognized as a permissible form of photo ID for pilots operating under FAA regulations. For pilots, acceptable forms of identification must explicitly meet safety and security guidelines established by the FAA. A US passport, military ID, and driver’s license are all valid forms of photo ID, as they verify both identity and certification for flight operations. The primary concern is ensuring that the identification presented is issued by a government authority and includes a photo, which supports the necessary verification processes pilots must adhere to. Hence, the green card does not fulfill the specific requirements set forth for pilots operating in the airspace.
